    Would an ohms variance of around .3 make a difference in power of a flipper?

    I need, according to the Gpadiators pin manual, a coil that reads 4.57 ohms. I replaced it with one that reads 4.8 ohms.

    Would this matter much in power of the flipper because the coil, sleeve, assembly are all new (right flipper) and the flipper just doesn't have the samr power as the left flipper.

    The reaction time is good, it just lacks the desired "pop"..it struggles to project the ball with the proper force. I can barely make it up the left ramp.

    The eos is set good.

    What about cleaning or replacing the CABINET'S flipper button contacts? You are also allowed to actually test the contacts with a meter.

    same clearance between flipper and pf bushing? EOS gap can be good - just make sure it isn't opening too early in the stroke of the flipper to kill the high current side. I don't know the tolerance of the coil but that doesn't seem unreasonable to me. At least i wouldn't suspect the coil as the main issue.

    Is the coil the same part number? If so I'd think that's normal variance or just meter inaccuracy.

    Have you rebuilt the flipper?

    Just holding the meters probes together might give you a reading of 0.3 ohms depending on meter and type of measurement. The coil is fine, your problem lies elsewhere.

    Quoted from Smart_Bomb:

    Are you sure you have enough pressure closing the contacts?
